Unleaded Fuel? No Problem!

The recent demonstration by the AOPA showcased the ongoing transition towards unleaded aviation fuel, highlighting a significant step in sustainable aviation. On October 31, AOPA President Mark Baker piloted a Beechcraft Baron, which uniquely ran on two different types of fuel: the newly FAA-approved 100-octane unleaded G100UL fuel in one engine and the traditional avgas in the other. This flight was not only a demonstration of the unleaded fuel’s efficacy but also its compatibility with existing aircraft engines, showing comparable performance to avgas during various flight maneuvers.

Furthering the push towards green aviation, the “National Celebration of GA Flyover” event on May 11 serves as a public demonstration of unleaded fuel’s potential. This event features a Beechcraft Baron C55, among other aircraft, flying over Washington, D.C., showcasing how general aviation can adapt to environmental needs while still performing effectively. The aircraft is part of a larger parade, demonstrating the practical use of G100UL fuel in a real-world setting, monitored for performance alongside traditional fuels.

As a company involved in the aviation industry, we’re proud to contribute to this environmental initiative with our fuel senders installed on aircraft like the Beechcraft Baron, ensuring accurate fuel measurement and safety in pioneering flights like these. The integration of our technology in such innovative endeavors underscores our commitment to supporting advancements in aviation fuel technology and sustainability.
